Seadoo Spark Tuning by Alt Tune raises the power to 110 HP on the Seadoo Spark range.  This is achieved by re calibrating / tuning the ignition tables, fueling tables and a range of other engine control tables inside the Bosch ME17 ECU.

The Seadoo Spark 90 is powered by 90 HP (ROTAX 900 HO ACE)  which is a 4 stroke engine controlled by a Bosch ME17 with a closed loop cooling system to keep the engine running at the ideal temperature, much like a car’s radiator. Also keeps out corrosive saltwater and debris.
